I think I am using timing. I compiled the simulator with:scons build/X86/gem5.opt an run the benchmark using these command:./build/X86/gem5.opt configs/example/se.py --caches --l1d_size=32kB --l1i_size=32kB --l2cache --l2_size=256kB --cmd=/scratch/rodri/spec2006/benchspec/CPU2006/403.gcc/run/run_base_train_rrr-static-gcc45-64bit.0000/gcc_base.rrr-static-gcc45-64bit --input=/scratch/rodri/spec2006/benchspec/CPU2006/403.gcc/run/run_base_train_rrr-static-gcc45-64bit.0000/integrate.in --option=" -o m5out/bench.s" --output=m5out/bench.out --errout=m5out/bench.err
For a real measure of performance do I need to use the -s option for se.py? > From: [email protected] > To: [email protected] > Date: Fri, 25 Jan 2013 13:01:36 +0000 > Subject: Re: [gem5-users] About statistics > > Atomic or timing? > > From: Rodrigo Reynolds Ram�rez > <[email protected]<mailto:[email protected]>> > Reply-To: gem5 users mailing list > <[email protected]<mailto:[email protected]>> > Date: Friday, 25 January 2013 12:26 > To: gem5-users <[email protected]<mailto:[email protected]>> > Subject: Re: [gem5-users] About statistics > > I am changing the latency of the simple memory in se.py, I changed the line > in this way: > > first case: > physmem = SimpleMemory(range=AddrRange("512MB"),latency="1000ns") > > second case: > physmem = SimpleMemory(range=AddrRange("512MB"),latency="30ns") > > I checked config.ini and the change is done but the results in stats.txt are > unchanged.
